2. Definition: refers to the bad ideas formed in feudal society.
3. The emergence of money worship, hedonism and extreme individualism is related to the long-term influence of feudal culture in China. Generally speaking, the mainstream of China's traditional culture is to despise interests and be ashamed of money. In the choice of righteousness and benefit, we always put righteousness in the first place, and advocate giving up life for righteousness and giving up life for righteousness. However, China's traditional culture has another side. Some people openly advocate egoism and hedonism, such as Yang Zhu in the Spring and Autumn Period, who publicly preached that "pulling out a dime is beneficial to the world, not to the world". There are also folk sayings that "people die for wealth, birds die for food", "people don't do it for themselves, and the devil takes the hindmost" and "money makes the mare go".
